...If I set one up fairly close to the top of the chain, do I really need something on the outside?
I'd rather not have a mech type thing, mainly cos they're £25 and weigh the same as an xtr front mech, of which I'll keep on if that's the case.
I could use a bb mounted roller at a guess?
Or I could bodge one using some stuff, like a roller and a clamp, a long bolt and some aluminium nylok nuts?
I think mamadirt bodged one and I recall someone bodging something out of that metal strapping..
ideas?
I think my budget is about £10.
